3 Protection
This section describes the short-circuit protection and fault-reporting circuitry of the TAS5342 device.
3.1 Short-Circuit Protection and Fault-Reporting Circuitry
The TAS5342 is a self-protecting device that provides fault reporting (including high-temperature
protection and short-circuit protection). The TAS5342 is configured in back-end auto-recovery mode and
therefore resets automatically after all errors (M1, M2, and M3 is set low); see the data sheet (
SLAS557 )
for further explanation. This mean that the device restart itself after an error occasion and reports shortly
thereafter through the SD error signal.
3.2 Fault Reporting
The OTW and SD outputs from TAS5342 indicate fault conditions. See the TAS5342 data manual for a
description of these pins.
